Thank you for this plugin which I've just downloaded. Could you tell me how I can change the ease-in and fading time please (either to slowly fade in a single image or to slowly fade between a slideshow)? I saw a previous older post where you gave the location below but this route doesn't work now so wondered where the correct file was now? Would be fantastic to have this as an option to change directly in the plugin settings in the future.
wp-content/plugins/background-manager/views/pub_footer.html.twig, on line 39 (simply replace "slow" with your value, in milliseconds - ie, 1000 = 1 second).
